Error with Warning! Legacy WGL is unable to select between different OpenGL versions
This is not a Blender question but I'll try to help you anyway.

Uninstall any display drivers you installed previously using DDU. Then just run a Windows update, that should load the most stable driver for you automatically. If that still doesn't work, go to amd.com, nvidia.com, or intel.com and find your driver from the Download/Support/Driver page.

A warning for the future, randomly renaming dlls is not a solution, it's a hack at best and is dangerous unless you understand what it's doing. In this case, you basically removed the OpenGL driver.
